For your repair work
Do not ignore the problems that every blow you will hit the concrete will bring immediately or later. Impact crushers, drills or tools such as hammers, chisels will cause dirt and noise, as well as cracks in the concrete and a second repair work. Do not think, do not break, do not have it broken, for plastering later, to look for a solution if there is an iron obstacle.
